Being a Mustachian doesn't mean not to have any hobbies that may cost a few bucks here and there. And $1K in coins, mate? I have about $12K in custom-built bicycles in my garage that I haven't touched in years. If I sell them, and I really should, I'll get perhaps 10 cents on the dollar for them. If you sell your coins one day, you probably don't lose any money, perhaps even make some.
I relative of my wife left her relative 64 LLardros, these Spanish porcelain figurines. She paid probably over $10K for them back in the day, and the street value is around $4,650 (we catalogued them). For the past months, we are trying to get rid of them for less than $2K, and there's not any interest so far. That's poor collecting.
My late dad collected coins as well. When he passed, I got 14 gold coins, mostly $20 coins starting in 1888. The oldest one is probably worth $1,600, give or take, and the other ones probably on average at least $1K. I haven't touched them since he passed in 2017, and I'm not worried about losing any significant money doing so.
Keep on collecting.
